查询词典 susceptible

Scientists at Oregon university argue in Nature magazine that their research with roundworms – which can self-fertilise or reproduce sexually – shows selfing populations are more susceptible to harmful genetic mutations and slow to adapt to swiftly changing environmental conditions.

In order to investigate the genetic variation of smut resistance in cross progenies and to construct the corresponding resistant and susceptible near-isogenic pools, some single lines derived from two cross hybrid combinations (CP84-1198×Ke5, ROC20×Gui73-167) were taken as the plant materials, and inoculation experiment was conducted in two crops of plant cane, and consequent relationship among the 5 indexes of infection was analyzed.

为研究甘蔗杂交后代黑穗病抗性的遗传变异，构建抗病、感病近等基因池，配置了2个杂交组合，其中组合1为CP84-1198×科5，组合2为ROC20×桂糖73-167，对2个组合部分后代进行2次新植人工接种黑穗病抗性鉴定，调查并分析了5个病害参数的关系。

Nested PCR analysis and southern hybridization analysis showed that no polymorphism between H.villosa, Pm97034 and susceptible parent Wan7 107 was detected with the clones from 6VS arm, whereas three clones from H.villosa genome DNA: RH42, RH55, and RH66 showed polymorphism. RGA6 cloned from H.villosa genome DNA was characterized identity to NBS, and show high homology to resistance genes as RPM1 and RPP13 in Arabiadopsis, LRR19 in wheat, and I2C-1 in tomato.cDNA library constructed from T.aestivum-H.villosa translocation line Pm97034 was screened by hybridization with RGA6. Four positive cDNA clones were obtained. R3-2-2 showing 60-90% identity with eukaryotic sulfite oxidases contained an open reading frame of 647bp encoding 140 amino acid, and contained a conserved Moco-dimer domain in the ORF. R6-2-2 showed an ORF containing an Euk-porin domain of 279aa with 20-40% identity to the eukaryotic voltage-dependent anion channel proteins. R8-1-1 showed a complete ORF of 1810bp encoding 493aa with 80-90% identity to plant catalases. R9-1-1 showed an ORF containing a BTB/POZ conserved domain of 204aa with 30-70% identity to pox virus and zinc finger proteins. R3-2-2 and R9-1-1 were the first cDNA clones containingconserved domain of SO and POZ respectively isolated from wheat. R8-1-1 contained a complete ORF with 81% identity to Cat-3. Aspects of the role of R8-1-1 may be same with Cat-3, and it would offer the opportunity for improvement of stress tolerance of wheat.

以RGA6为探针，筛选用抗白粉病小麦—簇毛麦易位系Pm97034构建的cDNA文库，得到了4个阳性克隆。R3-2-2与动植物的亚硫酸氧化酶(sulfite oxidase，SO)有60～90％的同源性，长度为647bp，编码140个氨基酸，具有开放阅读框并含有保守域Moco-dimer.R6-2-2与真核生物的VDAC(voltage-dependent anion chennel)蛋白有20～40％的同源性，长度为1047bp，编码279aa，是一个不完整的开放阅读框，预测结构具有Euk-porin结构域。R8-1-1与植物中已经克隆的过氧化氢酶有80～90％的同源性，长度为1810bp，编码493aa，具有完整的开放阅读框和过氧化氢氧化酶保守域。R9-1-1与动植物的POZ(pox virus and zinc finger protein)蛋白有30～70％的同源性，长度为1446bp，具有开放阅读框和BTB／POZ保守域。R3-2-2与R9-1-1是首次从小麦中克隆到的具有SO和POZ保守域的cDNA序列。R8-1-1具有完整的开放阅读框，与玉米Cat-3基因具有81％同源性，预测R8-1-1可能具有与Cat-3类似的功能，可为转基因小麦抗逆育种提供新的基因。
